Finding a useful test file should not slow down building or checking a product. The library brings common document, spreadsheet, image, data, and archive samples together in one place, with search, categories, and size options to make them easier to find.
Quick to browse
Search the catalogue or filter by documents, spreadsheets, images, data, and archives.
Free and straightforward
Browse and download samples without creating an account.
Formats and size options
The catalogue currently includes PDF, DOCX, TXT, XLSX, CSV, SVG, JSON, XML, HTML, and ZIP samples. Each listing provides size choices from about 1 KB to 10 MB. A generated file may be larger than the selected size when its original sample already exceeds that target.
These files are intended for development and demonstration. Check any sample before using it in a production workflow, and do not treat sample content as real or authoritative data.
